Discussion and Improvement on Empirical Mode Decomposition Algorithm

The stopping criteria for sifting and boundary effect are studied for Empirical Mode Decomposition(EMD) algorithm.The decomposition is enhanced by combining with the alternative EMD approach and the new stopping criteria.The alternative EMD approach circumvents the problem of boundary continuation in B-Spline interpolation,where the signal is assumed to be infinitely long.A discussion for boundary continuation with finite length is presented and its algorithm is developed.This research compensates for the existing approach and can serve as an applicable method in practice.Experiments show that the proposed method is effective.
